Well, with SCSI turned off, it didn't compile: drivers/block/cciss.c: In function `cciss_ioctl': drivers/block/cciss.c:1180: error: `SCSI_IOCTL_GET_IDLUN' undeclared (first use in this function) drivers/block/cciss.c:1180: error: (Each undeclared identifier is reported only once drivers/block/cciss.c:1180: error: for each function it appears in.) drivers/block/cciss.c:1181: error: `SCSI_IOCTL_GET_BUS_NUMBER' undeclared (first use in this function) make[2]: *** [drivers/block/cciss.o] Error 1 make[1]: *** [drivers/block] Error 2 make: *** [drivers] Error 2 -- steve -----Original Message----- From: James Bottomley [mailto:James.Bottomley@xxxxxxxxxxxx] Sent: Thu 4/12/2007 5:07 PM To: Mike Miller (OS Dev) Cc: akpm@xxxxxxxxxxxxxxxxxxxx; jens.axboe@xxxxxxxxxx; linux-kernel@xxxxxxxxxxxxxxx; linux-scsi@xxxxxxxxxxxxxxx; Cameron, Steve Subject: Re: [PATCH 1/1] cciss: kconfig patch to make cciss dependent onscsi for SG_IO ioctl On Thu, 2007-04-12 at 16:27 -0500, Mike Miller (OS Dev) wrote: > This kconfig patch makes cciss dependent on scsi for the new SG_IO ioctl we just > added.

Erm, I don't think this is necessary: SG_IO is a property of the block layer, not SCSI (as in it will work without SCSI even present). SCSI has a special driver: the sg driver that has its own implementation of SG_IO, but that's the only connection.
